Combine unloading auger drive
First Claim
1. In a combine having an operator'"'"'s station, a power source, and a grain tank, including a feeder auger on the bottom of the grain tank for moving grain from the grain tank to a discharger auger-type conveyor mounted on one side of the grain tank in crop-receiving relationship with the feeder auger and swingably mounted thereon for swinging between a generally fore and aft transport position and a range of unloading positions wherein the conveyor extends generally laterally outwardly and upwardly from the grain tank, the improvement comprising;
- a drive means operatively connected to the feeder auger and the discharge conveyor and including a clutch means selectively engageable to drivingly connect the feeder auger and the discharge conveyor to the power source;
a clutch actuating means operatively associated with the clutch means for controlling the engagement of the clutch means and including a control lever mounted at the operator'"'"'s station and shiftable between clutch engaging and clutch disengaging positions; and
interlock means operatively connected to the clutch actuating means and the discharge conveyor for preventing engagement of the clutch means when the discharge conveyor is not in one of its unloading positions.

Abstract
A self-propelled combine has an elevated grain tank with a laterally extending auger in the bottom of the tank for moving grain to an auger type discharge conveyor mounted on the side of the grain tank and swingable between a fore-and-aft transport position and alternate unloading positions wherein it extends outwardly and upwardly from the end of the grain tank auger. The discharge conveyor and grain tank auger are driven by a drive system that includes a clutch selectively actuated by the operator via a control lever at the operator'"'"'s station and a drive shaft mounted on and connected to the discharge conveyor and connected to the grain tank auger through a pair of universal joints at the axis of articulation of the discharge conveyor. An interlock device is provided between the control lever and the discharge conveyor, so that the clutch can be engaged to drive the discharge conveyor only when the discharge conveyor is in its extended or unloading position.
